Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to electronic teaching systems, and more particularly, to an audio/video teaching system using a network system and learning equipment.
2. Description of Related Art
Music is one of the most indispensable elements in human society. Our daily life is full of songs and music. Many people hope to learn correct singing or instrument-playing skills in order to improve their ability.
In general, there are two ways to learn singing or instrument-playing skills: direct learning and indirect learning. As to the direct learning way, a learner (or user) asks for guiding analysis from an experienced instructor in a face-to-face manner to correct shortcomings and add skills. For the indirect learning way, audio/video exemplification made by an instructor is stored in audio/video form into an audio/video storage device such as an optical disk. Accordingly, a user can play the audio/video exemplification at an appropriate learning site and time, using corresponding learning equipment (e.g., a computer).
However, for the direct leaning way, the user has to pay a high tuition fee. Moreover, the learner and the instructor have to agree on the learning site and time. For the indirect learning way, although costing less and allowing a user more flexibility in choosing a learning site and time, it has a serious drawback in that the user cannot get guiding analysis from an instructor, being only able to emulate the recordings and self-evaluate. As such, a user cannot readily find and correct shortcomings effectively.
Therefore, creating a way to provide an audio/video teaching system that works with a network system and learning equipment to allow skill evaluation and that provides ease of use, convenience and flexibility has becoming one of the most urgent needs in the art.

First Embodiment

FIG. 1 is a block diagram of an audio/video teaching system 1 of a first embodiment according to the present invention. The audio/video teaching system 1 comprises an audio/video capturing apparatus 10, an audio/video database 11, a connection module 12, and a selection module 13. Accordingly, a user (not shown) can use learning equipment 2 to connect to the audio/video teaching system 1 via a network system 3 that may be a wired network or a wireless network.
The audio/video capturing apparatus 10 captures audio/video exemplification for teaching and also guiding analysis corresponding to the audio/video exemplification. In the first embodiment, the audio/video exemplification refers to digital audio/video files of songs and/or music, and the guiding analysis refers to background stories, key issue reminders, stylistic elements, and/or vocal or playing skills that are produced by an instructor with respect to the aforesaid audio/video exemplification.
For example, the audio/video exemplification includes music video recordings of pop songs and/or exemplary video recordings of well-known music, and the guiding analysis includes teaching films that are produced for the pop songs and/or the well-known music. The content of the teaching films include source data, background stories, key issue reminders, lyrics and musical meanings, emotional analysis, breathing methods and/or vocal skills of pop songs and/or well-known music. The content of the teaching films may further include source data, background stories, key issue reminders, lyrics and music meanings, stylistic elements, emotional analysis and/or skills for using instruments of the well-known music. Note that the aforesaid guiding analysis may be presented in the digital audio/video files in the form of words, sounds and/or images.
The audio/video database 11 is connected to the audio/video capturing apparatus 10, for storing the audio/video exemplification and guiding analysis captured by the audio/video capturing apparatus 10.
The connection module 12 is connected to the network system 3, and receives via the network system 3 teaching requests and teaching instructions input by a user with the learning equipment 2. For example, the learning equipment 2 can be a computer, and the user inputs the teaching requests and teaching instructions with the keyboard and mouse of the computer. In the first embodiment, the connection module 12 further has an identity identifying module 120 that identifies the identity (e.g., account number and password) of a user when the user logs in to the audio/video teaching system 1 with the learning equipment 2.
The selection module 13 is connected to the connection module 12 and the audio/video database 11 for selecting corresponding audio/video exemplification and guiding analysis according to the teaching requests and teaching instructions input by the user via the connection module 12. Preferably, the selection module 13 adopts filtering methods and artificial intelligence algorithms to select the corresponding audio/video exemplification and guiding analysis.
In the first embodiment, the audio/video exemplification and guiding analysis selected by the selection module 13 are transmitted via the connection module 12 and the network system 3 to a storage apparatus of the learning equipment 2. The storage apparatus may include a hard disk or DRAM. Accordingly, the user can use the learning equipment 2 itself or a peripheral multi-media audio/video playing apparatus, such as a screen and speaker, to play the aforesaid audio/video exemplification and guiding analysis. In the first embodiment, the learning equipment 2 further comprises a comparison module 20.
